Abstract:
A non-warping and torque resistant structural panel including a top panel composed of four different size squares mounted on a base sheet. The squares when forming a pattern, have apices which are intermediate to and relatively offset from the apices of adjacent squares thereby forming relatively short vertically and horizontally extending intersecting lines, which resist warping and lateral torque.
